Microsoft.Extensions.Configuration.Abstractions

Provides abstractions of key-value pair based configuration.

Documentation can be found at https://learn.microsoft.com/dotnet/core/extensions/configuration

Example

The example below shows a small code sample using this library and trying out the ConfigurationKeyName attribute available since .NET 6:

public class MyClass
{
    [ConfigurationKeyName("named_property")]
    public string NamedProperty { get; set; }
}

Given the simple class above, we can create a dictionary to hold the configuration data and use it as the memory source to build a configuration section:

var dic = new Dictionary<string, string>
{
    {"named_property", "value for named property"},
};

var config = new ConfigurationBuilder()
    .AddInMemoryCollection(dic)
    .Build();

var options = config.Get<MyClass>();
Console.WriteLine(options.NamedProperty); // returns "value for named property"

Contribution Bar

• We consider new features, new APIs, bug fixes, and performance changes

The APIs and functionality are mature, but do get extended occasionally.

Deployment

Microsoft.Extensions.Configuration.Abstractions is included in the ASP.NET Core shared framework. The package is deployed as out-of-band (OOB) too and can be referenced into projects directly.
